Compression Joint Structure for Multi-Tool Pipe Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compression connection joints are limited in application range due to compatibility issues with different types of compression tools, restricting their use to specific market areas where matching tools are available.
Innovation Solution
A compression connection joint design that accommodates various types of compression rings, including U-type, H-type, RF-type, TH-type, B-type, and RFZ-type, through a structure with specific toothed rings and grooves, enabling universal compatibility and effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If compression connection joints are designed with specific toothed ring positions for different compression tools, then compatibility with various compression tools (U-type, H-type, RF-type, TH-type, B-type, RFZ-type) is improved, but device complexity increases due to multiple toothed ring configurations
Solution Approach 1:
The insertion portion is designed with a universal toothed ring structure that can accommodate multiple types of compression tools (U-type, H-type, RF-type, TH-type, B-type, and RFZ-type). The toothed rings are positioned and configured to work with all six tool types, allowing a single joint design to serve multiple functions and tool compatibility without requiring different joint variants for each tool type.
2Reliability
If multiple sealing grooves and toothed rings are added to ensure sealing performance, then sealing reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The sealing structure is segmented into three distinct sealing grooves positioned at different locations on the insertion portion. Each sealing groove can contain a sealing ring or rely on the metal-to-metal contact of the insertion portion itself. This segmentation allows the sealing function to be distributed across multiple locations, improving overall sealing reliability while maintaining a relatively simple manufacturing process for each individual groove.
3Adaptability or versatility
If the insertion portion structure is optimized for universal compatibility, then adaptability to different compression tools is improved, but precision of toothed ring positioning becomes more difficult to control
Solution Approach 1:
The insertion portion features locally optimized toothed ring structures at specific positions that are tailored to work with different compression tool types. Each region of the insertion portion has toothed rings configured with specific dimensions and positions that accommodate the characteristics of different tool types (U-type, H-type, RF-type, etc.), allowing high precision at each local position while maintaining overall universal compatibility.

AI summary
A compression connection joint and a pipe. The compression connection joint comprises a joint body (1), a compressing sleeve (2), a retaining ring (3), and sealing rings (4). The joint body comprises an insertion portion (5), the retaining ring being disposed at a root portion (6) of the insertion portion, and the compressing sleeve being sleeved on the insertion portion and forming, together with the insertion portion and the retaining ring, an accommodating cavity for insertion of a pipe. Three sealing grooves (701, 702, 703) are sequentially disposed on the outer surface of the insertion portion along the axial direction, one sealing ring being correspondingly disposed within each sealing groove, and one first square gear ring (8) and at least two first inverted gear rings (9) being sequentially disposed on the insertion portion between two adjacent sealing grooves along the direction close to the root portion of the insertion portion. The compression connection joint is convenient and easy to operate, achieves sealing and leakage prevention, and is suited to six compression ring types, namely U, H, RF, TH, B, and RFZ, having a wide application range.
